Authorities have identified the suspect in a deadly bombing at an Ariana Grande concert in Manchester, England, Monday night.

According to CBS News, Salman Abedi, 23, has been named as the suicide bomber who killed 22 people and injured dozens more at Monday night’s concert at Manchester Arena.

Abedi died in the blast, which appears to have been a suicide bombing.

The suspect reportedly made the bomb himself. According to The Sun, the bomb have have contained nails.

CBS News reports that Abedi was previously known to British authorities.

A second suspect, also a 23-year-old man, was reportedly arrested on Tuesday. He has not been identified, and his possible role in the attack is not known.

Police and British Prime Minister Theresa May told reporters that investigators are working to determine whether “was acting alone, or was part of a wider group.”

U.S. intelligence sources told CBS News they had not verified an earlier claim made by ISIS that the terror group was responsible for the attack. The statement issued by ISIS reportedly got some facts wrong about the bombing, and did not name the suspect.

As Crime Online previously reported, an 8-year-old girl and a 16-year-old student were among those killed in the attack.
